Overview
Uninsured Motorist Insurance (UM) provides benefits when you are injured by a driver who has no insurance or not enough insurance to cover your losses. This coverage is available on many personal and business auto policies and is designed to protect your medical expenses and lost income after a covered accident.
UM can work alongside your medical or disability plans, often filling gaps those policies do not cover—such as compensation for pain and suffering or certain out-of-pocket costs.
Key takeaways
- UM helps cover medical bills and lost wages when an at-fault driver lacks sufficient insurance.
- It can be broader than health insurance and may not include deductibles or coinsurance.
- Policy limits vary by state and by the specific policy you buy.
How it works
After an accident where the other driver is at fault but underinsured or uninsured, you submit a claim under your UM coverage. Your insurer evaluates losses much like the at-fault driver's carrier would and pays up to your policy limits for eligible injury-related claims.
In some states you may have separate limits for UM and underinsured motorist (UIM) coverage, and in others the protections are combined or optional; check your policy details carefully for how claims are handled.
What it may cover (and what it may not)
UM typically covers reasonable medical expenses and a portion of lost income directly tied to the injury from the accident. It may also pay for pain and suffering in situations where health insurance would not.
UM generally does not cover routine vehicle repairs unless you have a specific endorsement that extends coverage to physical damage, and coverage can exclude certain drivers or uses depending on your policy language and state law.
Common mistakes to avoid
Do not assume your health insurance will fully protect you after an uninsured or underinsured motorist accident—health plans often exclude non-economic damages and may impose deductibles or limits.
Avoid choosing the minimum possible UM limits without considering income, medical costs, and long-term effects from a serious injury; inadequate limits can leave you responsible for large expenses.
Questions to ask an agent
Ask about how UM is structured on your policy, whether limits are per person or per accident, and which family members and permissive drivers are covered.
Request clarification on state-specific options and whether you need separate endorsements for physical damage or pass-through benefits if you have other health coverage.
Next steps
Review your current auto policy declarations page and compare your liability limits with available UM limits; if you want detailed program options, see Uninsured Motorist Insurance Overview for related explanations and scenarios.
If you carry other liability concerns or want broader protection above your auto limits, consider adding Personal Umbrella Insurance to extend coverage beyond primary policy caps.
When you are ready to update coverages or compare quotes, talk to an agent who can review options tailored to your business or personal auto exposures.
Frequently Asked Questions
What is the difference between UM and UIM?
UM applies when the at-fault driver has no insurance, while UIM applies when the at-fault driver’s limits are too low to cover your losses; both address gaps in the other driver’s coverage.
Will my health insurance pay first or does UM pay first?
Order of payment depends on your policy terms and state rules; sometimes health insurance pays initially and UM reimburses or supplements certain costs, but this varies by situation.
Are there deductibles or coinsurance on UM claims?
Most UM coverages do not have deductibles, but policy language can vary, so check your contract for any cost-sharing provisions.
Can UM cover passengers in my vehicle?
Typically yes—passengers who are injured while in your vehicle are often covered under your UM limits if the at-fault driver is uninsured or underinsured.
Should business vehicles carry UM?
Yes, business autos can face uninsured drivers just like personal vehicles, so carrying appropriate UM/UIM limits on commercial auto policies is commonly recommended.
